Desalination

With continuing growth in the reverse osmosis water treatment industry and the finite lifespan of the membranes, the number of membrane modules requiring disposal is expected to drastically increase over time. This study aimed to provide a quantitative assessment of the environmental impact from memb

Produced water management is one of the key challenges faced by the oil and gas industry globally. Specifically, the gas industry in Qatar is challenged to minimize the produced/process water (PPW) volumes injected into disposal wells to ensure long term sustainability of the reservoirs. This researc

Conventional processes involved in water treatment, either in water treatment plants or reverse osmosis desalination plants, have encountered several obstacles that have severely affected their performances and efficiencies. Pollution of natural water resources, increasing demand and overuse of clean

Reverse osmosis (RO) based desalination is one of the most important and widely recognized technologies for production of fresh water from saline water. Since its conception and initiation, a significant development has been witnessed in this technology w.r.t. materials, synthesis techniques, modifica

• CHP–H2CO3 is a high osmotic pressure thermolytic draw solute. • CHP–H2CO3 solutions produce relatively high forward osmosis water fluxes. • Low grade heat should be sufficient to degas CHP–H2CO3 solutions. • CHP–H2CO3 solutions display good material/membrane compatibility. • Water flux and reverse dr

Global water planners are increasingly considering seawater desalination as an alternative to traditional freshwater supplies. Since desalination is both expensive and energy intensive, taking advantage of favorable natural and societal conditions while siting desalination facilities can provide sig

This study focuses on the water quality assessment (feed, product and brine) of the pilot adsorption desalination (AD) plant. Seawater from the Red Sea is used as feed to the AD plant. Water quality tests are evaluated by complying the Environmental Protection Agency (EPA) standards with major prima

The present study evaluated the performance of pressure retarded osmosis–reverse osmosis (PRO–RO) process for power generation and seawater desalination. Two pre-developed software were used separately to estimate the performance of forward osmosis (FO) and RO process. The draw and feed solutions in

This paper introduces a process synthesis strategy and optimization approach that accounts for boron removal considerations in Seawater Reverse Osmosis (SWRO) network design. The overall aim is to provide an improved understating of the performance of SWRO networks when specific requirements on boron

The effect of exposure reverse osmosis (RO) membrane to antiscalants (AS) on consequent organic fouling during seawater desalination was analyzed. Membrane surface properties (hydrophobicity and zeta potential) were altered upon the conditioning of the membrane with AS during the desalination proces
